iFixit posted thier teardown of the Kindle Fire HDX 7" this morning. I have gone step by step and gathered my thoughts on the teardown, in the hopes they might explain some of the new news and/or technical bits for those eagerly awaiting their new HDX.
* Amazon clearly partnered with Qualcomm's early access program for the snapdragon 800 to produce the HDX as a "release wave" device, which makes sense given they would need expertise from the chip vendor to minimize how much skills updates the lab team would need to make. Most of the power management and basic system set of ICs is nearly identical to the reference dragonboard development kit. Also clear from the ecosystem of chips in this device is that Amazon partnered with LG on key aspects of the display and things like the battery charging system. In many ways the architecture of this device, is an LG G2 in a larger form factor, mated to Amazon's ecosystem.
* The level of repairability with the HDX is far inferior to prior versions of the Kindle Fire. This is due mainly to the form factor. As you work to put all of these components in close proximity, reducing weight and thickness, one of the trade-offs is that you begin having to very closely "layer" the components together. What the teardown shows is a lot of adhesive used.
- Break the screen and it very quickly becomes impractical to repair. Replace the device.
- Amazon appears to have gone overboard to make the internals on this device tough. Our complaints about stuff coming loose like the charging port means that Amazon has used screws, adhesive, and even the way things are layered to try and make the internals tougher. The downside this creates is individual components become hard to work with.
* Amazon has used a higher end charging chip (the SMB349) in the HDX. The neat thing about this is that Amazon can update the firmware on it, it can be programmed to function more efficiently.
- Amazon can "fix" problems discovered with how the device charges later via system updates.
- Amazon can potentially enable the kindle to output from its own battery to other devices via the microUSB port. Up to .9A, which is just under the "standard" USB spec.
EDIT: Will add further observations as replies.
